IPC: G03G21/10
Filed: 1987-12-25
Abstract: PURPOSE:To prevent a vibration and a sound generated from the tip part of a cleaning member by providing an elastic member between a cleaning member and a fixed member such as a part of a cleaning case, etc. CONSTITUTION:The title device is structured so that an elastic member 18 comes into contact with the upper face of a blade 12, and also, comes into contact with a part 21-1 of a cleaning case 21. In this case, in order to suppress a vibration of the blade 12, it is necessary that the elastic member 18 is adhering closely enough to the upper face of the blade 12. Accordingly, when a photosensitive body 4 rotates in the direction as shown by the arrow, the blade 12 is bent, and a vibration generated in the tip part is absorbed by the elastic member 18 pushed from behind by one part 21-1 of the cleaning case. In such a way, the generation of a sound which follows up the vibration is prevented.

IPC: B60W10/06
Filed: 1998-11-18
Abstract: PROBLEM TO BE SOLVED: To prevent engine stopping at the time of starting immediately after low temperature starting. SOLUTION: A motor 62 cranks an engine 61. Air intake valve closing timing is roughly at a delay angle position before starting an engine, a variable valve system device 63 comes to be in a working possible state simultaneously when hydraulic pressure in the inside of the engine is generated and thereafter, opening and closing timing of the air intake valve can be controlled. Closing timing of the air intake valve at the time when engine torque durable for actual travelling is generated is previously decided as a threshold value by a setting means 64. A travelling prohibition means 65 prohibits travelling at the time of starting the engine, and a detection means 66 detects actual air intake valve closing timing in this travelling probition state.  A judging means 67 judges whether the actual air intake valve closing timing exceeds the threshold value and comes to be on a advance angle side or not from comparison of the detection value and the threshold value, and travelling prohibition is released as a travelling prohibition release means 68 finishes starting at the time when the actual air intake valve closing timing exceeds the threshold value and comes to be on the advance angle side from this judgement result.

Title: Method for multi-dimensional transfer of data in data-processing system
Inventor: NATAN BARON
IPC: G06F13/28
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To reduce or remove the overhead of software by realizing a multi- dimensional transfer at a few number of times of interruption in a data processing system. SOLUTION: An initial counter value is loaded to a transfer counter register 76 divided into independently controlled three sections for executing three- dimensional DMA transfer. Data are transferred from continuously generated addresses at the first prescribed number of times decided by the value of the first section of the register 76. An offset value is added to an address generated at last. This processing is repeated at the second prescribed number of times. Another offset value is added to the generated address. The above-mentioned processing is repeated at the number of times decided by the third section of the register 76. The initial counter value is reloaded from a backup register 77 to the register 76, and when a new transferring request requests the same counter value as the previous transfer, it is judged that a DMA controller 80 is prepared.
